Answer:
Correct answer:
The equilibrium expression is defined as the ratio of the concentration of products divided by the concentration of the reactants. Each reactant or product is raised to the power corresponding to its coefficient in the balanced chemical equation.

cccfffffff
Explanation:
Integrated rate law for second order kinetics is:
Where, is the final initial concentration
is the initial concentration = 0.355 M
k is the rate constant = 0.540 (Ms)⁻¹
t is the time = 15.9 seconds
Applying the values in the above expression as:-
<u>11.4 M of will be left after 15.9 seconds have passed.</u>

Explanation:
cold air is denser than hot air so it sinks.
Answer: 1+
Justification:
The ionization energy is the amount of energy needed to loose electrons and becomes ions.
The first ionization energy is the energy needed to liberate one one electron and form the ion with oxidation state 1+.
The second ionization energy is the energy to release a second electron and form the ion with oxidation state 2+.
The third ionization energy is the energy to leave a third electron free and form the ion with oxidation state 3+.
The relatively low first ionization energy of element 2, shows it it will lose an electron easily to form the ion with oxidations state 1+.
The second and third ionization energies are very high meaning that the ions with oxidation staes 2+ and 3+ will not be formed.
Therefore, the answer is that the expected oxidation state for the most common ion of element 2 is 1+.
Answer:
<h3>The answer is 0.42 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 8.11 g
volume = final volume of water - initial volume of water
volume = 44.72 - 25.26 = 19.46 mL
We have
We have the final answer as
<h3>0.42 g/mL</h3>
Hope this helps you
